R&S TS-EMF EMF Measurement System At a glance In combination with Rohde & Schwarz spectrum analyzers, the R&S TS-EMF measurement system detects high-frequency electromagnetic fields in the environment (EMF). The isotropic antenna, together with the software, which has been specifically designed for EMF measurements, allows simple and precise evaluation of total and individual emissions on site. Measuring EMF emissions in line with national and international standards provides a basis for ensuring that transmitter systems comply with the applicable limits and for communicating this to the general public. The key criterion is a precise, easy-to-make on-site measurement. The R&S TS-EMF measurement system supports users by providing automated test sequences, including preconfigured measurement packets. The isotropic antenna detects fields independent of their direction and polarization. A wide range of Rohde & Schwarz spectrum analyzers and test receivers is available for performing such measurements. In particular, the compact one-box solution with the R&S FSL spectrum analyzer allows measurements to be performed even in locations that are difficult to access.

Safety based on exact measurements for reproducible and reliable results Evaluation of total emissions, individual radio services or individual frequencies Discussion about radiation exposure frequently focuses on individual transmitter sites or radio services. However, it is important in all cases to measure and assess the total emissions. The R&S TS-EMF measurement system provides an overview of the total emissions along with the individual results, e.g. for specific radio services. Moreover, for each subrange, the individual frequencies can be accessed to identify the emitters. Emissions that are not allocated to any measurement packet are handled as Intermediate and output. Measurements in line with all common EMF standards and measurement methods International and national EMF regulations protect the general public as well as workers against electromagnetic radiation. The R&S TS-EMF covers the requirements of ICNIRP, EN 50400 and EN 50499 as well as many national standards that are derived from these standards. All EMF measurement methods used in actual practice are covered by a single measurement system: Fast overview measurement Provides a summary of the emissions scenario in the measurement range within seconds Average/peak value versus time Measures the maximum and average value of signals, e.g. measurement of a six-minute interval in line with ICNIRP Grid method Using different measurement points, a spatial area is covered, e.g. the human torso (example: EN 50400, EN 50499) Stirring method The peak value for a measurement range is exactly determined by manually moving the antenna in a defined spatial range Long-term measurement Changes in the field strength of individual radio services and the total value are determined over a user-definable period of time The R&S TS-EMF enables users to immediately decide on site which meas urement method (or combination of measurement methods) is to be used for a particular test location. Software supports them by providing identical operation and evaluation for all measurement methods. Fast overview of the total exposure and individual emissions immediately after the measurement. 4 TS-EMF_dat_en_0758-2777-12_v0501.indd 4 11.04.2016 09:36:09
Correct evaluation of complex scenarios or RF signals In an EMF measurement, it is important to ensure that signals with different bandwidths, modulation schemes and timing structures are correctly detected. The R&S TS-EMF measurement system meets this requirement by covering frequency subranges with individually configured measurement packets. This makes it possible to correctly measure a mixture of different signals. The R&S TS-EMF offers two different measurement modes: R&S RFEX-Fast The R&S RFEX-Fast measurement software allows the user to select the required measurement packets for any particular measurement. Each measurement packet is defined on the basis of the frequency range and signal type. The signal type (e.g. FM, DVB-T/T2, DAB, GSM, WCDMA, LTE, WIFI, DECT) automatically defines all other measurement parameters. Standard measurements are covered in a straightforward manner with this approach. Simply selecting the radio services ensures a correct measurement R&S RFEX The R&S RFEX measurement software handles special signal types and can also be used for detailed investigations. The different measurement parameters can be set individually. A library of sample measurement packets and a detailed description support users during the configuration process R&S RFEX allows users to investigate special problems by directly configuring the measurement parameters. Both measurement software packages (R&S RFEX-Fast for fast standard measurements and R&S RFEX for greater flexibility) are an integral part of the R&S TS-EMF. Excellent reproducibility using automated measurements Using automated test sequences makes on-site work easier and also reduces the risk of errors. The measurement settings and (when using a GPS receiver) the location are automatically documented. This simplifies quality assurance and allows comparative measurement campaigns with identical settings for detecting changes that have occurred at a site. R&S RFEX-Fast software: easy measurement configuration for all measurement methods. Rohde & Schwarz R&S TS-EMF EMF Measurement System 5 TS-EMF_dat_en_0758-2777-12_v0501.indd 5 11.04.2016 09:36:09
Efficient on-site measurements Fast, efficient measurements thanks to predefined test routines Predefined test routines and an automated test sequence allow measurements without a high expenditure on personnel along with a fast response to special requests and discussions or questions at the test site. On-site interpretation of results using integrated report generation The automatically generated test report is useful for immediate evaluation of the measurement. The graphical presentation offers a fast overview, while the table shows precise results. Results are displayed as absolute values or as a of the limit value. Fast evaluation allows immediate discussion and interpretation of the results and can be used to decide whether additional measurements are needed. Measurement results are also accessible in MS Excel format and are available for creating a custom test report. Easy adaptation to local conditions When making a measurement with measurement packets, other radio services can be added or removed to adapt the predefined measurement packets to local conditions. Even new services that have not yet been defined can be added to the R&S RFEX-Fast measurement software simply by indicating the frequency range and signal type. They can then be measured separately. Versatile use due to the compact one-box solution with the R&S FSL spectrum analyzer EMF measurement sites are often difficult to reach. The mobility provided by the R&S TS-EMF is increased further through the one-box solution using the R&S FSL spectrum analyzer. The R&S RFEX-Fast measurement software runs directly on the compact analyzer and is operated solely via the instrument s keypad. The isotropic antenna, the software and the analyzer form the measurement system. R&S FSL with isotropic antenna. 6 TS-EMF_dat_en_0758-2777-12_v0501.indd 6 11.04.2016 09:36:11
Suitable for a wide range of applications Investigation of specific problems or radio signals by directly setting individual measurement parameters Besides handling standard measurements, the R&S RFEX measurement software also allows detailed configuration of the measurement parameters. This makes the R&S TS EMF an ideal tool for further in-depth analysis, as required for many studies, for example. Additional manual measurements using a fullfledged spectrum analyzer In many cases, the EMF measurement is only one out of a whole series of measurements, e.g. when commissioning base stations or for providers of measurement services. For efficient operation, it is important that the spectrum analyzer or EMI test receiver can be used without restrictions for other measurements, too. Optional storage of raw measurement data for further in-depth result evaluation For the automatically generated report at the end of a measurement, the measurement results are compressed, especially in case of long measurement cycles. Optional storage of the raw data 1) allows subsequent precision analysis with exact timing and frequency information. This enables users to trace and characterize measurement results in detail even after the measurement has been completed. 1) ASCII files with all measured isotropic field strength values exceeding an adjustable threshold. Precise extrapolation for WCDMA and LTE signals using demodulation In the case of wireless services, frequency-selective measurements have often to be combined with specialized measurement methods for various radio services. These methods allow exact extrapolation to maximum system utilization and allocation of emissions to the appropriate base station. For WCDMA base stations, this involves demodulation of the CPICH control channel on which data is sent at constant power and a fixed ratio to the maximum power of the base station. A similar procedure is used for LTE, i. e. the decoding and power measurement of the reference symbols on antennas 1 and 2 and of the S-SCH and P-SCH synchronization channels. Especially the decoding of the reference symbols is very popular because it allows the different MIMO channels to be measured independently. The R&S TS-EMF can decode all required values fast and accurately when combined with the R&S TSME and R&S TSMW radio network analyzers. Equipped with the required options, the R&S TS EMF/R&S TSME covers the common wireless services with a frequency range from 350 MHz to 4.4 GHz in one very compact system. The R&S TS EMF/R&S TSMW combination also includes other services, such as radio and TV with a frequency range from 30 MHz to 6 GHz. The system provides the following features: Automatic decoding of all received codes Identification of base station and sector using the decoded cell ID High measurement rate (approx. five measurements/s) to enable all EMF measurement methods, including the stirring method, even for decoding High sensitivity and wide dynamic range Large number of parallel rake receivers for correct evaluation even of signals with many reflections In addition, the decoding functionality of the R&S FSH is supported by the R&S TS-EMF with the R&S TSEMF-K23 option. This allows automatic decoding of the field strength of the surrounding base stations as well as automatic report generation. Combination of R&S TS-EMF and R&S TSME for decoding LTE and WCDMA signals and for frequency-selective measurements.

Future-ready Coverage of the complete frequency range from 9 khz to 6 GHz using isotropic antennas Three isotropic antennas are used to cover the entire frequency range from 9 khz to 6 GHz: Isotropic loop antenna, 9 khz to 200 MHz Isotropic antenna, 30 MHz to 3 GHz Isotropic antenna, 700 MHz to 6 GHz Providing a frequency range from 9 khz to 6 GHz, the antennas cover all common radio services as well as important standards such as EN 50400 and EN 50492. All services in the frequency range from 700 MHz to 6 GHz important to mobile radio and broadband services are covered with a single measurement without changing antennas. For frequencies below 10 MHz, the additional linear summation of the field strengths required by ICNIRP and other standards is performed automatically. In addition, the R&S TS-EMF supports any other nonisotropic antennas, allowing the entire frequency range of the spectrum analyzer to be used. Measurements of advanced radio services with wide bandwidths and high crest factors The transmission methods used in today s radio services are undergoing continuous enhancement. Current services such as DVB-T/T2, WCDMA, LTE, and WLAN use wide bandwidths and high crest factors. The R&S TS-EMF measurement system meets the requirements of current and future services with its true RMS detector and large selection of standard measurement bandwidths. In addition, special channel filters as well as the channel power measurement functions are supported depending on the spectrum analyzer used. The R&S TS-EMF and a suitable spectrum analyzer are therefore an ideal combination for handling a wide variety of measurements.
